Perihemorrhagic hypoperfusion probably is a consequence of reduced metabolic demand (diaschisis) rather than a sign of ischemia. We found no evidence for a perihemorrhagic and potentially salvageable ischemic penumbra in hyperacute ICH. Further studies should address metabolic, toxic, apoptotic, and microvascular aspects.
Schellinger et al. (Tue,) studied this question.
